Earlier today, director Bryan Singer teased the possibility of an X-Men and Fantastic Four crossover, and it seems we’d likely see the younger cast alongside Marvel’s First Family if that were to happen.

X-Men: Apocalypse introduces the superheroes’ most epic threat yet in the form of the titular Apocalypse (Isaac), who may not only be the oldest mutant, but the first one ever. Recent set photos have teased destruction in Cairo, hinting at Storm’s origin story. And we also know that Storm, Psylocke, Angel/Archangel and Magneto will serve as Apocalypse’s Four Horsemen.
